PRO3 Racing Gauge Series | Specs & Compatibility – Shadow

Shadow PRO3 is purpose-built for modified and performance vehicles, preserving the rapid sweep visual feedback of traditional needle racing gauges while combining electronic sensing and digital signal processing. It delivers precise vehicle monitoring alongside the direct, intuitive reading experience of physical needles.PRO3 features 270° high-resolution needle drive technology, paired with a 1088-microstep stepper motor and high-refresh-rate control, enabling needles to respond quickly and finely to data changes. When facing rapidly fluctuating values such as boost pressure or oil pressure, drivers can not only read current values but also intuitively judge vehicle condition changes from the needle's speed and sweep range.The PRO3 electronic racing gauge series is available in 52mm and 60mm sizes, covering water temperature, oil temperature, oil pressure, turbo boost, fuel pressure, exhaust gas temperature, and voltage. Different specifications offer PSI/BAR pressure units and °C/°F temperature units.The gauge body features a full aluminum alloy housing and aluminum alloy bezel ring, with a specially designed diffuser sheet that distributes LED backlighting more evenly. Daytime readings are crisp and clear, while at night the needles and scale markings are rendered with distinct depth — balancing legibility with the visual character of classic round racing gauges.PRO3 uses an independent single-gauge design, allowing drivers to freely select gauge types and quantities based on vehicle configuration and actual monitoring needs, assembling a vehicle monitoring setup that best fits their requirements.Fast response, intuitive reading — every vehicle condition change is directly conveyed through the needle.
